7 Claims.

This invention relates to reelsor spools to be. used for the storage andshipment of cords. It has for its objects:

First, to provide a new and improved reel.

Second, to provide such areel'made primarily of paperboard or the like.

Third, to provide such a reel which is of rigid construction.

Fourth, to provide such a reel with suitable l0 bearings which permitthe mounting of the reel on an axle or spindle, either of the-machineemployed in making the cord to be wound thereon, or to permit the reelto serve as the supply reel on the machine employing the cord.

Other objects and advantages pertaining to details and economies ofconstruction and operation will appearv from the description to follow.The invention is pointed out in the claims. A preferred embodiment of myinvention is illustrated in the accompanying drawing, in which:

Fig. 1 is a perspective view of my improved reel.

Fig. 2 is an end elevational view of the reel.

Fig. 8 is a detail sectional view taken on the line 3-3 of Fig. 1, drawnto a larger scale than in Fig. 1. D

Fig. 4 is a detail sectional view taken on line 4-4 of Figs. 1 and 3. v

Fig. 5 is a perspective'view of the plate forming the bearing for thereel.

Fig. 6 is a view showing certain of the parts in disassembledrelationship.

Referring to the drawing, the reel is shown with heads I and a barrel 2.The heads I are preferably paperboard disks and each head is providedwith a centrally disposed square aperture 3.

The barrel 2 is made up of plates 4 of sheet metal.

These plates are preferably square and are disposed parallel to the headI when they are in place. The plates have central bearing apertures 0 5and ears 6 extending from their ends.

An inner core .7 is made up by wrapping a sheet l of cardboard aroundthe plates 4. The edges of the sheet of cardboard overlap as shown inFig. 3 and staples 9 hold the cardboard in position. Apertures ill inthe cardboard sheet 8 receive the ears 6 of the plates 4 and tend tohold the plates in the desired position.

The inner core 1 fits within and extends through the central aperture 3of the head I. Flaps ll extend from the end edges of the core I and liealong the outer surface of the head I. Staples i2 passing through theheadand the flaps hold them in position. I

An outer cylindrical core l3, preferably of paper, fits around the innercore I, touching at the corners of the inner core as shown in Fig. 3. N

The inner core thus serves to support and position the outer core andthe outer core I3 is fitted between the heads I and serves as a spacerand bracing member for holding them in position.

It will be apparent that this arrangement provides an extremely rigid,light weight reel of cardboard. The inner core with its flaps tends tohold the head i in place and the outer core it serves to brace the headsand to serve as a barrel 1 for receiving the cord wound on the spool.The plates 4 with their bearing apertures 5 make it possible for a shaftto be properly held and centered to permit. the reel to be used eitheras a supply reel on a machine using the cord or as a reel to receivecord from the machine making it.

The reel may be easily and simply assembled from inexpensive cardboardsuch as strawboard and may be put together by the simple use of wirestaples which are in common use in the box making art.

Having thus described my invention, what I claiiin as new and desire tosecure by Letters Pat en s:

1. In a reel, the combination of a pair of cardboard heads with centralsquare apertures, a barrel made up of a pair of square sheet metalplates disposed parallel to said heads and centrally apertured to formbearings and having ears projecting from their edges and an inner coreof square cross section formed of cardboard wrapped to overlappingrelation around said plates and stapled and apertured to receive saidears to hold said plates in position, said inner core being fitted inthe apertures of said heads and having flaps extending from the endedges thereof and lying on the outer faces of said heads and stapledthereto, and an outer cylindrical core fitted around and supported bysaid inner-core and fitted between and bracing said heads.

2. In a reel, the combination of a pair of cardboard heads with centralpolygonal apertures, a barrel made up of a pair of polygonal sheet metalplates disposed parallel to said heads and centrally apertured to formbearings and having ears projecting from their edges, and an inner coreof polygonal cross section formed of cardboard wrapped around saidplates and stapled and apertured to receive said ears to hold saidplates in position, said inner core being fitted in the apertures ofsaid heads and having flaps extending from the endedges thereof andlying on the outer faces of said heads and stapled thereto, and an outercylindrical core fitted around and supported by said inner core andfitted between and bracing said heads.

3; In-a reel, the combination of a pair of cardvlooard'heads with squareapertures, a barrel made up or a pair of square sheet metal platesdisposed parallel to said heads and centrally apertured to form bearingsand having ears projecting from their edges, and an inner core of squarecross section formed or cardboard wrapped around said plates andapertured to receive said ears to hold said plates in position, saidinner core being fitted in the apertures of said heads and having fiapsextending from the end edges thereof and lying on the outer races ofsaid heads, and an outer cylindrical core fitted around and supported bysaid inner core and fitted between and bracing said heads.

4. In a reel, the combination of a pair of cardboard heads with centralpolygonal apertures, a barrel made up of a pair of polygonal sheet metalplates disposed parallel to said heads and centrally apertured to formbearings and having ears projecting from their edges and an inner coreof polygonal cross section formed of cardboard wrapped around saidplates and apertured to receive said ears to hold said plates inposition, said inner core being fitted in the apertures 01 said headsand having flaps extending from the end edges thereof and lying on theouter faces of said heads, and an outer cylindrical core fitted aroundand supported by said inner core and fitted between and bracing saidheads.

5. In a reel, the combination of a pair 0! heads with central polygonalapertures, a barrel made up of a pair or polygonal plates disposedparallel to said heads and centrally apertured to form bearings andhaving ears projecting rrom their edges, and an inner core of polygonalcross section tormed of sheet material wrapped around said plates andapertured to receive said ears to hold said plates in position, saidinner core being fitted in the apertures 01 said heads and having fiapsextending from the end edgesthereo! and lying on the outer races oi saidheads, and an outer core fitted around and supported by said inner coreand fitted between and bracing said heads.
